.. l GOLD-WASHER.

SPECIFICATION forming part of Letters Patent No. 279,122, dated June 12, 1883.

Application filed June 6, 1882. (No model.)

To all whom it may concern Be it known that we, 0. S. Entries and HARRY E. WILsoN, of Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented a new and useful Improvement in Gold- YVashers, of which the following is a full, clear, and exact description.

Our improvements relate to apparatus for washing gold-bearing gravels and sands for re moval of the gold. I

Heretofore a large percentage of the fine gold has been lost, and the apparatus used for that purpose are expensive to manufacture and unsatisfactory in use.

The object of the present device is to effect the desired result in an economical, expeditious, and reliable manner; and to this end the illvention consists in the peculiar construction and arrangement of parts, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate cor responding parts in all the figures.

Figure 1 is avertical longitudinal section of our improved apparatus. Fig. -2 is a 'plan view of the same. Fig. 3 is a detail plan view, showing the devices for vibrating the slats. Figs. 4 and 5 are detail. side and section elevations of the same.

A is a flume in which the gravel, sand, or

other gold-bearing material is to be placed.

B is a slatted platform or screen, the slats being pivoted at their ends, so that they may be adjusted at any desired angle to .give a greater or less opening, as the character of the material. being worked may require. This screen is placed at the end of the flume A, and is hinged or pivoted at its upper end at a, so that it may be set at any desired inclination.

E is the chute at the outer end of screen B, for carrying off the washed gr. vel and dirt.

. D is a platform fixed below the screen B to receive the gold screenings and fine material.

H is an inclosed box provided with a removable side or door, and placed beneath the outer end of the platform D,- so as to receive the screenings therefrom.

m m are mats placed in the box H, one above another, and attached by hinges d to the opposite sides of the box alternately.

Z Z'are arms supporting the mats, and adj ustable to vary their inclination.

I is an outlet-pipe at the lower end of the box H. 4 V v F is a flushing-box placed at the upper end of the platform D and provided with a slide, 1).

G is a tube for supplying water to the flushing-box for the purpose of flushing the platform D.

The mats m are made offine wirecloth, cocoa matting, hair-cloth, or any fibrous material which will give a strong firm nap, the object being that the nap shall remain upright under pressure.

The operation is as follows: The gold-bearing material is washed from the flume A upon the screen 13, and the gravel, dirt, and lighter n'iaterials are carried over the screen and dis charged by the chute E. The heavy screenings containing the gold is caught upon the platform D, from which it passes upon the mats in succession, which retain all the fine gold. Theupper mat retains most of the gold, those beneath serving to catch what may remain. The mats when full can readily be re moved and washed out in tanks. The screen, constructed with the pivoted slats, will not be liable to choke, and can be easily cleaned. All that is necessary is to stop the feed a moment and raisethe slats, and the screen will clean itself. Each alternate slat, or the whole screen, is given a slight vibratory movement to prevent choking. In Fig. 3 means for imparting such movement are shown.

1 is a pulley on a shaft, S, supported in bearings T. On each end of the shaft is an eccentric or a crank, I).

R are pitmen connecting the shaft with the vibratory bars 0, to which the cranks of alternate slats are attached. The shaft is to be driven by a small water-wheel or other power.

XVe do not limit ourselves to any special material for the mats, nor to the use of any particular number.

The apparatus can be made of any suitable capacity, according to requirements.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a goltlv'ashing apparatus, the combination, with the screen 13, formed of a frame nation, with the sereeneBfahd platformflljqf, Witnesses:
